ULP-SRP: Ultra low power Samsung Reconfigurable Processor for biomedical applications

The latest biomedical applications require low energy consumption, high performance and wide energy-performance scalability to adapt to various working environments. This paper presents ULP-SRP, an energy efficient reconfigurable processor for the biomedical applications. ULP-SRP uses a Coarse Grained Reconfigurable Array (CGRA) for high performance data processing with low energy consumption. For the scalability, we propose three performance modes and Unified Memory Architecture (UMA). Energy optimization is accomplished by run-time mode switching along with automatic power gating. Experimental results show that ULP-SRP achieved 46.1% energy reduction compared to previous works.
